Thüringen.

From Old High German Duringa. From the name of the Thüringer (“Thuringians”), a people who are attested since at least 480 when Sidonius Apollinaris mentions them (as Toringus m), and potentially earlier around 150 when Ptolemy mentions the Τευριοχαῖμαι (Teuriokhaîmai). Their name was traditionally connected to that of the Hermunduren, but this is discredited by modern etymologists on phonological grounds; instead, a connection to the Turones is sometimes proposed. Grahn-Hoek alternatively proposes a connection to the Thervingi (authors have at least mixed up the two groups since ancient times on account of the similarity of their names), particularly a subgroup living along the Τύρας (Túras).
